Notes on the cars:

March 722 [27] (Allan Lader): Allan Lader (Gresham, OR) had a black #2 March 722 for 1972. As his main focus in 1972 was Formula 5000, he only raced the car in two Pro FB races and in the Sep 1972 Lime Rock FA race when it was fitted with a BDA and ran in the Formula A class. It was entered by Pacifico Inc. and also, at Laguna Seca in May 1972, by Pierres Motors Racing. In 1973, Robert Hall (Oakland, CA) raced a black March 722 that was said to be ex-Lader. He raced this car in SCCA National and Regional races over the next three seasons or longer.

Brabham BT29 (Jon Milledge): Jim Gutfreund (Des Moines, Iowa) bought a new Brabham BT29 for 1970 and ran it in Midwest Div Formula B, winning two races and leading the division until his BRM-built Ford twin-cam blew. He sold the car to Archie Snider for 1971 and Snider continued with the BRM engine until joining forces with Jon Milledge who crewed the car for Snider in Regionals while racing it in Nationals and in Pro events. They continued with the car through 1972 and into 1973, before Snider replaced it with a GRD. It then went to Larry Wright to replace his earlier BT29 that he'd wrecked in June 1973. Wright kept the car until 1974 after which he retired and sold the car to "an unknown guy who lived in the Sierra Madre area of So Cal, near Pasadena".

Brabham BT35 [6] (Nick Cook): Chassis number given for Nick Cook's car in Autosport report of Arco Trophy race at Castle Combe, April 12, 1971, where the car debuts [AS 15 Apr 1971 p20]. Chassis number observed by Adam Ferrington on Cook's car at Oulton Park, 18 Mar 1972. Does not appear in the UK after the end of April and probably the car taken by Cook to the USA to use in the SCCA series. Used by Rob Turnbull in hillclimbs in 1974 and then sold to Andrew Fraser in 1975.

Lola T240 [HU4] (Syd Demovsky): New to Syd Demovsky (Chicago, IL) and his red #11 Demovsky Racing Lola T240 in the 1971 Pro FB series. Retained for 1972 and again did a full season, still red and still using #11. Subsequent history unknown. A car with this chassis number raced by Bob Juggins in 1996/97.

Brabham BT29 [1] (John Angus): John Angus bought the first BT29, ordering the car as early as late summer of 1968 but taking delivery in August 1969. He ran it in Regionals in late 1969 before participating in the Pro series in 1970. He swapped from a Vegantune to a Racing Services engine for 1971 and continued in Nationals. Angus continued with the car in 1972, when Ron Dykes also drove it in the Bogotá races and again in 1973, when the car continued to be competitive at National level. Unknown after the end of the 1973 season.

Brabham BT35 [32] (Gordon Strom): Raúl Pérez Gama was one of several Mexican customers of Fred Opert racing in the early 1970s. For 1972, he had a brand new orange-and-yellow Brabham BT35 and raced as part of the Fred Opert Racing team in Pro Formula B events with entry number #66. He retained the car for the two Bogotá races in early 1972 after which BT35-32 has been indentified as the car driven in SCCA events by Gordon Strom (Santa Cruz, CA or Sunnyvale, CA) in 1972 and for the following three seasons, retaining the car's original orange and yellow colours throughout. For 1976, Strom acquired a Chevron B29 and the Brabham may have been traded back to Fred Opert.

Chevron B20 [72-3] (Bobby Brown): Sold via Fred Opert to Bobby Brown (Hicksville, NY) for SCCA Formula B. Third and first in the two Bogotá races early in 1972, then raced in the JAP GP at Fuji in May. Also won the Pro FB race at Lime Rock in July. Likely to be the B20 raced by Dan Carmichael (Columbus, OH) at the 1972 SCCA Runoffs. Raced by Chip Mead (Dayton, OH) at Mosport Park in July 1973. To Freeman Racing for 1974, and raced by Price Cobb in the Pro Formula Atlantic races that season. Advertised by Cobb in early 1975, then advertised by Richard Jackson (Dallas, TX) in August 1975 as "ex-Brown", and February 1976. Next seen when sold by a dealer, Paul Lindell (Houston, TX), to James Sawyer in January 1978. From Sawyer to Jeff McKay (Tacoma, WA) then on to Walt Pawluczkowycz (Evergreen, CO). Sold by Pawluczkowycz to Steve Marschman (Idaho Falls, Idaho) in May 2004.

March 722 (Olney "Bill" Mairs): Olney "Bill" Mairs (Malibu, CA) raced an orange #12 March 722 in three Pro races during the 1972 season. This would have been a new car but nothing is currently known of the car's fate.

Brabham BT29 [44] (Larry Wright): This late BT29 remained unused in 1970 and was sold by Charlie Hayes to Larry Wright (Riverside, CA) in Dec 1970, taking Wright's Chevron B15 in part exchange. Wright raced the orange-and-yellow #83 Brabham in Pro events and in SCCA National and Regional events on the west coast. In June 1973, he wrecked the car in practice for a National at Laguna Seca and replaced it with the ex-Archie Snider BT29. The damaged chassis went to Marc Bahner in 1974 who eventually repaired it and sold it to Lou Pavesi in 1980. It later passed to Steve Pike in Australia in 1993 and then to Jim McConville in 1998.

Lola T240 (Bill Middleton): Bill Middleton (Newport Beach, CA) bought a yellow #31 Lola T240 late in the 1971 Southern Pacific FB season to replace an elderly Brabham BT21C. He won enough points in this car to clinch second place in the division. Retained for 1972 and used in both Pro and SPDiv events, winning the division by a considerable margin. Last seen in late July 1972, after which Middleton acquired a Brabham BT38B. Subsequent history unknown.

Brabham BT29 (Bob Criss): In 1972, Stephen M. Cole (Orange, CA) entered a Brabham BT29 in Pro Formula B races for Bob Criss (originally from Terre Haute, IN, but by 1972 of Newport Beach, CA). The car was blue and wore #64 when raced by Criss. Cole himself also raced in Nationals and is thought to have been racing the same car at Riverside in May 1972. Criss signed with Mary & Tom Page's Page Racing for Indy racing in 1973 but was killed in a testing session in April 1973. Criss was Robert Dale Criss, born 1938, and should not be confused with the Bob Criss from Bethel Park, PA, who drove an Austin-Healey Sprite in SCCA racing as a member of Steel Cities Region at about this time. Nothing more is known of the Brabham.

Brabham BT14 [FL-3-65] (Steve Jizmagian): This BT14 was bought new by John Mitchell and raced in northern English libre racing in 1965 and 1966. It was sold late 1967 to Steve Pfeiffer (San Francisco, CA) and equipped with a BRM Phase 4 twin-cam for 1968 Formula B racing, now described as a BT21. It was sold to Bruce Redding (Monterey, CA) for 1969 but crashed early in the season and extensively rebuilt. Redding thereafter entered it in 1969 and 1970 as a Ford Special, Gravelle Special or even as a Honda Special. It was later sold to Steve Jizmagian (San Francisco, CA) in early 1971 and crashed again, then to Tom Gouldstone (Santa Rosa, CA/Napa, CA) in November 1972 and crashed again - each time at Laguna Seca - and then to Dick McGovern in 1978. It was retained by McGovern until 1994 when sold to George Goodare (Sydney, Australia) and restored. Later to Brian Wilson in September 2000 then to John Gale in November 2001. Sold to Richard Longes late 2008 and raced in 2009 Tasman Revival races.

Brabham BT38B (Nick Craw): Nick Craw (Washington, DC) raced a #71 Brabham BT38 in the 1972 SCCA Pro Formula B series but is only known to have started two races. The car was described as blue/yellow or yellow and was entered by Fred Opert Racing. It is likely that this was a brand new BT38B. In February 1973, the "ex-Craw" car was advertised by Opert as "4 races from new". Nothing more known.

The identification of individual cars in these results is based on the material presented elsewhere in this site and may in some cases contradict the organisers' orginal results.

1970 US FB results were compiled from Autoweek reports by Jim Thurman; 1971 results were transcribed from Autoweek by Allen Brown and 1972 results were compiled by Chris Townsend from an SCCA results publication.

The US Formula B series did not continue in 1973 but a race was organised in Caracas in March 1973 that fits here probably better than anywhere else, as do the occasional SCCA F/Atlantic and FB races in 1974 and 1975.
